Digestion - Simple Explanation
youtube
Food moves through your GI tract by a process called peristalsis. The large, hollow organs of your GI tract contain a layer of muscle that enables their walls to move. The movement pushes food and liquid through your GI tract and mixes the contents within each organ. The muscle behind the food contracts and squeezes the food forward, while the muscle in front of the food relaxes to allow the food to move.
Mouth. Food starts to move through your GI tract when you eat. When you swallow, your tongue pushes the food into your throat. A small flap of tissue, called the epiglottis, folds over your windpipe to prevent choking and the food passes into your esophagus.
Esophagus. Once you begin swallowing, the process becomes automatic. Your brain signals the muscles of the esophagus and peristalsis begins.
Lower esophageal sphincter. When food reaches the end of your esophagus, a ringlike muscle—called the lower esophageal sphincter —relaxes and lets food pass into your stomach. This sphincter usually stays closed to keep what’s in your stomach from flowing back into your esophagus.
Stomach. After food enters your stomach, the stomach muscles mix the food and liquid with digestive juices. The stomach slowly empties its contents, called chyme, into your small intestine.
Small intestine. The muscles of the small intestine mix food with digestive juices from the pancreas, liver, and intestine, and push the mixture forward for further digestion. The walls of the small intestine absorb water and the digested nutrients into your bloodstream. As peristalsis continues, the waste products of the digestive process move into the large intestine.
Large intestine. Waste products from the digestive process include undigested parts of food, fluid, and older cells from the lining of your GI tract. The large intestine absorbs water and changes the waste from liquid into stool. Peristalsis helps move the stool into your rectum.
Rectum. The lower end of your large intestine, the rectum, stores stool until it pushes stool out of your anus during a bowel movement

•9April2021•
The train from Raleigh to Charlotte is back up and running full time, which means I don’t have to drive when going to visit the boyfriend anymore.
This week has been somewhat of an emotionally stressful rollercoaster, because a lot of little things are changing all at once that’s making a it a collectively large thing.
I’m preparing for medical school applications (that open next month 🙃), and found out that I need to take two classes this summer in order to meet application requirements for a couple of schools. Which means I might end up graduating from grad school in August, earlier than anticipated. Which means I’ll need to find a job, because I’ll need a source of income.
This week has been a lot. But just now, I had an hour long call with a friend who’s currently in her second year at one of the public institutions in the state, who went through the application process for both public institutions in the state, and she helped me map out how the next few months will look, how I shouldn’t stress about submitting the very first day, and to wait until I can present my strongest application, which will be towards the end of the summer.
If you’ve been around for a a while, you might be wondering about whether I’ll retake the MCAT or not. And I...still haven’t decided. The schools take scores from as late as September. So stay tuned.

26/100 days of productivity
Hello! I hope your day went well!
I am so proud of me today, because I pushed myself into studying evolution and all the eras and periods and epochs.... It's a lot to memorize, but I guess I can manage to remember basic information :D
Weekend is coming, time to finish homeworks and tests in Moodle and also time to pamper myself and relax a bit :D
Picture shows me during the weekend.

ATTENTION Healthcare workers and those studying to be in healthcare!
I am currently conducting research through the University of Florida on implicit bias in healthcare and how our current and future health professionals are exposed and or dealing with it.
I created a short and completely anonymous survey, and I would appreciate any responses as it takes part in the research.

25/100 days of productivity
Today was such a long day. I was not busy with classes, I studied for the usual amount of time, but something felt strange. I have no idea why I felt like that.
I finished my maths homework, studied taxonomy of protozoa and some physiology of them.
I also downloaded quizlet, so I might create some flashcard tonight.
One thing that makes me happy is that the covid situation is getting better, less patients are hospitalised, but our university already stated we will be online schooled until the end of the semester. Maybe exams will be in present form. We will see.
Also, my medschool entrance exams are aproaching, i still have 2 months left. I plan to end my biology revision by the end of the april and then do it all over again until exams. I am already getting nervous.

Online classes are so boring in my opinion. Many of my professors just talk for the whole time, they don’t ask questions, there’s no interaction between us. It has definitely made learning worse, and I feel like I’m not learning anything. What has been you guys experience with online classes? Let me know in the comments👇🏾✨• • • • • • • • • • #nursingschool #nursingstudent #studentnurse #prenursingstudent #collegestudents #medstudent #premed #premedstudent #pastudent #crnastudent #srna #fnpstudent #npstudent #otstudent #nursesofinstagram #nurse (at New York, New York) https://www.instagram.com/p/CNYhx97h4G0/?igshid=c7hok3amhocf

I encourage anyone who’s learning A&P to watch Sam Webster on YouTube. He’s so fun and chill. I love watching his videos as a break from studying.

Listen, do I feel like I have studied a lot this week? Maybe. Have I accomplished things to get closer to feeling more prepared for applying to Medical school in just over a month? Most definitely. Will I be able to binge the last two episodes of RWBY Volume 8 sometime this weekend? Hopefully. Do I still have a fuckton of stuff on my plate that needs to be handled sometime this month? Abso-fucking-lutely.
Anyways, I feel pretty good about myself and my productivity this week as I now have exactly 4 weeks until I retake the MCAT. But I also have been able to recognize when I get hit with the pesky anxiety and have been to take some deep breaths and reset myself. Whoo, I'm pumped so weekend here I come!
